If weight is not an issue,then why do we have Carbon Fiber everything,spinners,wing tubes,landing gear,tail wheels,push rods,etc.Kevlar cables for pull-pull,flying wires,smaller and smaller servos,recievers,Titanium control links,Duralite batteries,lighter engines,the list goes on and on.If weight wasn't an issue,I don't think you would see all this light weight stuff available.Just bolt a .46 on your Pico Stick(and I am sure some of you have)and see how well it flies.No doubt "Light is Right"
